Most cosmetics come in plain cardboard boxes and some people keep them, because they want to have the igredients and all the stuff that this product promises to offer, while others keep them just because they like having their stuff in their boxes. I generally throw away all the boxes into the recycle bin, unless it's something really cute and artistic, like Jelly Pong Pong's products. I find it such a hassle to use products that are in boxes, so I eventually end up not using them.
What about you? Do you keep them or throw them away just like me?
